Abstract

In this age of globalization, many advances were achieved according to technological advances. Agricultural technology is therefore evolving drastically compared to what it was before. Technology heavily affects agricultural variables. Agriculture previously relied on all labour. But now, it's all easy, as only one machine is in control. A more convenient digital system replaced previously necessary labour. The agricultural method created has made fertilization and watering easier. However, the fertilization process has not yet achieved progress that is equivalent to other processes. The fertilization process still uses the workforce in controlling the rate of crop fertilizer even though fertilizer has used the latest flow system. Grown crops need enough nutrients to stay fertile. The process of fertilizing crops is not as easy as expected because the plants planted require different nutrients according to the plants. Because humans have limited abilities, electronic systems are created using special components to help compensate for human shortcomings. Therefore, the purpose of this project developed is to develop a plc based system for automatic mixing of AB nutrients for multiple types of plants, automatic fertilizer dripping based on soil moisture and humidity sensor. Besides that,farmers can monitor the current level of fertilizer in the tank and the status of the pump, valve and other equipment. As a result, this project will combine with this hydroponic system to take over the work of mixing fertilizer according to the plants that the user selects. The ratio of the desired nutrients of multiple types of plants has been set in Programmable Logic Controller (PLC). The help of soil moisture and humidity sensor will help this system optimise the fertilizer system to the plant. The Programmable Logic Controller (PLC)system used in thissystem simplifies the process of controlling fertilization activities. Control of the fertilizer process is also easier with the visual facilities displayed on the touchscreen provided. Aside from that, farmers can monitor the whole process using an application that can warn them when the device is fully operational. The presence of this project would promote future agricultural activities and assist in the development of agricultural skill.
